Storm Arwen has blown sections of roof off the site of a Saundersfoot restaurant and bar.
Janz Restaurant and BB's Bar at Broadfield Farm Holiday Park sustained damage at around 8am on Saturday as high winds battered the UK.
The caravan park, a family business, told WalesOnline the chunks of roof torn off were above the toilets and games room.
"I wasn't there but friends on the site were filming it and sending it to me," said the owner. "We can't do anything about it right now, it's too dangerous. We've got to let things happen.
"The bar itself is fine because it's at the other side of the building, but we can't get to assess it really until we're in touch with insurance on Monday. We're going to get water damage after this. It is difficult. We're still in the middle of it and we don't know what's going to happen. We're in limbo."
Janz Restaurant and BB's Bar are housed in a converted farm building. The bar opened in 1994 before the restaurant started trading in 2000. The caravan park is seasonal, with the bar normally open and the restaurant closed at this time of year.
The Met Office had an amber weather warning in place for Saundersfoot and other parts of west Wales overnight until 9am on Saturday.
A less severe yellow warning for wind is set to be in place across all of Wales from 9am until 6pm. High winds have seen all train lines blocked on Saturday morning between Cardiff and Swansea due to a fallen tree, while there are closures on routes including the M4 and the M48 Severn Bridge.
The Met Office has warned of a possible danger to life from Storm Arwen in Wales. A primary school headteacher was killed in Northern Ireland when a tree fell on his car and a second man was killed by a falling tree in Cumbria.
